Reviewers described the flavor and texture of this drink as "very odd." The protein in the water comes from whey, leaving the drink with a milky taste that does not meld well with the coconut flavor.

Greater Than

The taste of this drink was described as just plain bad and "kind of sour." Still, the beverage boasts half the sugar and two times the electrolytes of leading sports drinks.

Each serving has 30 calories, 135 of potassium, 7 grams of sugar and 8 grams of carbohydrates.

PowerBar

Powerbar Perform was described as a watery, lemon-lime flavor, however consumers can add more powder to fit their tastes. With a dose of sodium, carbohydrate and 10 grams of sugar, this blend was made to help you replace electrolytes lost during a hard workout and to maximize fluid consumption during exercise.

Muscle Milk

While the smell was reminiscent of graham crackers, the taste was alternately described as vanilla, flavored soy milk and "an aspartame-covered banana split." Still, this drink packs 25 grams of protein and manages a creamy texture while being lactose free.

Pur Pak

Reminiscent of EmergenC, the Pur Pak has a sour taste and the smell of a creamsicle. The product is full of antioxidants, vitamins and minerals, including coenzyme Q10, vitamin C, iron, potassium, glucosamine and chondroiton. Each tablet has only 15 calories and two grams of sugar and is made without artificial colors, dyes or sweeteners.

Greater Than

A step up from the Berry Blue, this Greater Than product still left something to be desired. The taste begins as "light and fruity, but a little bland" and ends "cardboard-y."

ZYM

With a light lemon flavor reminiscent of Jell-o, Zym was described as "the least sugary of the bunch." In a single tablet, there are just seven calories, a single gram of sugar and nutrients including vitamin C and vitamin B6.

Vitamin Water

Reviewers were divided on this product. While some described it as too sweet, another was "pleasantly surprised byt eh lack of sweetness." While there are no calories in this drink, you'll still get a heavy dose of vitamins B6, B12 and C, as well as zinc. The first ingredient is reverse osmosis water and vegetable juice is used to create the hot pink color.

CytoSport

With a tart, grape taste, this product serves up 90 calories, 12 grams of sugar and nutrients including vitamins A and C.

Vitalyte

The Sweet Tarts taste of of Vitalyte left reviewers unenthusiastic, but willing to try the product again. The drink has 100 calories per serving and a potent dose of B vitamins to help you stay focused and mentally tough.

Nuun

This slightly carbonated drink was described as having a cola or bubble gum taste. The electrolyte blend has no sugar, but a solid serving of potassium, sodium and magnesium, as well as 20 milligrams of caffeine. No artificial flavors or colors are used in Nuun products.

Muscle Milk

Tasters described Muscle Milk Cookies N' Creme as a "protein-packed pinch in the mouth" with mocha and vanilla flavors. They also commented on its exceptionally sweet taste:

"I have a hard time believing this is any better than drinking a milkshake," one wrote. But can a milkshake boast 25 grams of protein and just three grams of sugar? (Note: we're still not sure how Muscle Milk gets its sweet taste, given that no artificial sweeteners were listed.)

Gatorade

In 2013, Gatorade re-launched Frost, a drink that serves up 80 calories, 21 grams of sugar and 45 milligrams of potassium. Reviewers gave the light, sweet flavor solid scores.

Gatorade

Far and away, the winner of this competition was the chocolate protein shake from Gatorade. One reviewer enthusiastically referred to the flavor as the "rich chocolate-milk taste you fondly remember being served at the school cafeteria." At 270 calories, this drink packs 20 grams of protein, 20 grams of sugar and 35 percent of your daily calcium.
